Suggested March 2024 Making Sense Of Data: Considering Top Data Mining TechniquesDeriving actionable insights from your data with essential data mining techniques.
Businesses today have access to massive amounts of data than ever before. These voluminous data are typically collected and stored in both structured and unstructured forms. These data are gleaned from various sources such as customer data, transactions, third-party vendors, and more. However, to make sense of the data is much challenging and requires relevant skills and tools and techniques to excerpt meaningful information from it.Data Cleaning
As businesses often gather raw data, it requires to be analyzed and formatted accurately. By appropriate data cleaning, businesses can understand and prepare the data in different analytic methods. Typically, data cleaning and preparation involves distinct elements of data modeling, transformation, data migration, ETL, ELT, data integration, and aggregation.Association
Association defines to identify a pattern in a transaction. It specifies that certain data, or events found in data, are related to other data or data-driven events. This technique is used to conduct market basket analysis, which is done to find out all those products that customers buy together regularly. It is useful in understanding customers’ shopping behaviors, providing businesses the opportunity to study sales data of the past and then predict future buying trends.Clustering
Clustering is the process of finding groups and clusters in the data in such a way that the degree of association between two objects is highest if they belong to the same group and lowest otherwise. Unlike classification that puts objects into predefined classes, clustering for data puts objects in classes that are defined by it. Essentially, clustering mechanisms use graphics to define where the distribution of data is in relation to different sorts of metrics. This technique also uses different colors to show the distribution of data.Classification
This data mining technique is generally used to classify different data in different classes. It is similar to clustering in a way as it also fragments data records into different segments. But unlike clustering, data analysts in classification analysis would know about different classes or clusters. They would even apply algorithms to determine how new data should be classified.Outlier Detection
Simply finding patterns in data may not give a clear understanding that businesses want. Outlier analysis or outlier mining, which is the most crucial data mining technique, helps organizations determine anomalies in datasets. Outlier detection generally refers to the observation of data items in a dataset that do not match an expected pattern or expected behavior. Once businesses find deviations in their data, it becomes easier to understand the reason for anomalies and better prepare for any future occurrences to achieve business objectives.Regression
This data mining technique refers to the process of detecting and analyzing the relationship between variables in a dataset. Regression analysis can help businesses understand the characteristic value of the dependent variable changes if any one of the independent variables is varied. It is primarily a form of planning and modeling and can be used to project certain costs, relying on other factors such as availability, consumer demand, and competition.Sequential Patterns
It is particularly useful for data mining transactional data and focuses on divulging a series of events that take place in a sequence. It encompasses discovering interesting subsequences in a set of sequences, where the stake of a sequence can be measured in terms of various criteria like length, occurrence frequency, and so on. Once a company understands sequential patterns, it can recommend additional items to customers to spur sales.Visualization

However, to make sense of the data is much challenging and requires relevant skills and tools and techniques to excerpt meaningful information from it. Data mining here has a role to play in extracting information from a given data set, identifying trends, patterns, and useful data. Data mining refers to the usage of refined data analysis tools to discover previously unknown, valid patterns, and relationships in huge data sets. It integrates statistical models, machine learning techniques, and mathematical algorithms, such as neural networks, to derive insight.

It grants users’ insight into data based on sensory perceptions that people can see. Also, data visualizations can be used through dashboards to unveil insights. Instead of simply using numerical outputs of statistical models, the enterprise can base dashboards on different metrics and use visualizations to highlight patterns in data visually.
You're reading Making Sense Of Data: Considering Top Data Mining Techniques
Data mining is the process of examining vast quantities of data in order to make a statistically likely prediction. Data mining could be used, for instance, to identify when high spending customers interact with your business, to determine which promotions succeed, or explore the impact of the weather on your business.
Data analytics and the growth in both structured and unstructured data has also prompted data mining techniques to change, since companies are now dealing with larger data sets with more varied content. Additionally, artificial intelligence and machine learning are automating the process of data mining.
Regardless of the technique, data mining typically evolves over three steps:
Exploration: First you must prepare the data, paring down what you need and don’t need, eliminating duplicates or useless data, and narrowing your data collection to just what you can use.
Modeling: Build your statistical models with the goal of evaluating which will give the best and most accurate predictions. This can be time-consuming as you apply different models to the same data set over and over again (which can be processor-intensive) and then compare the results.
Deployment: In this final stage you test your model, against both old data and new data, to generate predictions or estimates of the expected outcome.
Data mining is an highly effective process – with the right technique. The challenge is choosing the best technique for your situation, because there are many to choose from and some are better suited to different kinds of data than others. So what are the major techniques?
This form of analysis is used to classify different data in different classes. Classification is similar to clustering in that it also segments data records into different segments called classes. In classification, the structure or identity of the data is known. A popular example is e-mail to label email as legitimate or as spam, based on known patterns.
The opposite of classification, clustering is a form of analysis with the structure of the data is discovered as it is processed by being compared to similar data. It deals more with the unknown, unlike classification.
This is the process of examining data for errors that may require further evaluation and human intervention to either use the data or discard it.
A statistical process for estimating the relationships between variables which helps you understand the characteristic value of the dependent variable changes. Generally used for predictions, it helps to determine if any one of the independent variables is varied, so if you change one variable, a separate variable is affected.
This technique is what data mining is all about. It uses past data to predict future actions or behaviors. The simplest example is examining a person’s credit history to make a loan decision. Induction is similar in that it asks if a given action occurs, then another and another again, then we can expect this result.
Exactly as it sounds, summarization present a mode compact representation of the data set, thoroughly processed and modeled to give a clear overview of the results.
One of the many forms of data mining, sequential patterns are specifically designed to discover a sequential series of events. It is one of the more common forms of mining as data by default is recorded sequentially, such as sales patterns over the course of a day.
Decision tree learning is part of a predictive model where decisions are made based on steps or observations. It predicts the value of a variable based on several inputs. It’s basically an overcharged “If-Then” statement, making decisions on the answers it gets to the question it asks.
This is one of the most basic techniques in data mining. You simply learn to recognize patterns in your data sets, such as regular increases and decreases in foot traffic during the day or week or when certain products tend to sell more often, such as beer on a football weekend.
While most data mining techniques focus on prediction based on past data, statistics focuses on probabilistic models, specifically inference. In short, it’s much more of an educated guess. Statistics is only about quantifying data, whereas data mining builds models to detect patterns in data.
Data visualization is the process of conveying information that has been processed in a simple to understand visual form, such as charts, graphs, digital images, and animation. There are a number of visualization tools, starting with Microsoft Excel but also RapidMiner, WEKA, the R programming language, and Orange.
Neural network data mining is the process of gathering and extracting data by recognizing existing patterns in a database using an artificial neural network. An artificial neural network is structured like the neural network in humans, where neurons are the conduits for the five senses. An artificial neural network acts as a conduit for input but is a complex mathematical equation that processes data rather than feels sensory input.
You can’t have data mining without data warehousing. Data warehouses are the databases where structured data resides and is processed and prepared for mining. It does the task of sorting data, classifying it, discarding unusable data and setting up metadata.
This is a method to identify interesting relations and interdependencies between different variables in large databases. This technique can help you find hidden patterns in the data that that might not otherwise be clear or obvious. It’s often used in machine learning.
Data processing tends to be immediate and the results are often used, stored, or discarded, with new results generated at a later date. In some cases, though, things like decision trees are not built with a single pass of the data but over time, as new data comes in, and the tree is populated and expanded. So long-term processing is done as data is added to existing models and the model expands.
Regardless of which specific technique you use, here are key data mining best practices to help you maximize the value of your process. They can be applied to any of the 15 aforementioned techniques.
Preserve the data. This should be obvious. Data must be maintained militantly, and it must not be archived, deleted, or overwritten once processed. You went through a lot of trouble to get that data prepared for generating insight, now vigilance must be applied to maintenance.
Have a clear idea of what you want out of the data. This predicates your sampling and modeling efforts, never mind your searches. The first question is what do you want out of this strategy, such as knowing customer behaviors.
Have a clear modeling technique. Be prepared to go through many modeling prototypes as you narrow down your data ranges and the questions you are asking. If you aren’t getting the answers you want, ask them a different way.
Clearly identify the business problems. Be specific, don’t just say sell more stuff. Identify fine grain issues, determine where they occur in the sale, pre- or post-, and what the problem actually is.
Look at post-sale as well. Many mining efforts focus on getting the sale but what happens after the sale — returns, cancellations, refunds, exchanges, rebates, write-offs – are equally important because they are a portent to future sales. They help identifying customers who will be more or less likely to make future purchases.
Deploy on the front lines. It’s too easy leave the data mining inside the corporate firewall, since that’s where the warehouse is located and all data comes in. But preparatory work on the data before it is sent in can be done in remote sites, as can application of sales, marketing, and customer relations models.
Facebook knows us. Exceptionally well.
Facebook tracks who we talk to, what we talk about, what we like, what we’re interested in. It tracks where we are and what transactions we conduct. Facebook can pick your face out of other people’s pictures and automatically tag you in media. It can even find you in the background of crowd shots (“isn’t it cool that I’ve been tagged in so many pictures?”).
After gathering all this personal data, who does Facebook sell it to? Any buyer who can afford it. Even foreign actors, as we saw in the 2024 election. If there’s a small smidgen of our intimate life that Facebook can sell, it will do so.
Think about it: Facebook is enabling the subversion of our highly personal social networks for profit and undue political influence. Which raises the questions: Is consumer capitalism – with any sense of safeguards – working anymore? Are the likes of Facebook, Google, and other online giants simply too big to suffer economic penalties for violating public trust? If so, we are on a slippery slope indeed.
It’s not that we haven’t been warned about the dangers of sharing personal data online. And many of us do take precautions with some of our sensitive data. Yet as a group we think all those online complimentary services are worth the loss of privacy, bit by bit.
So Facebook (and other Web giants) accumulate all our personal data points over time. The more data there is in one place, the more value it has for data mining. Over time, and in context of other individual data points, it becomes Big Data. Using data integration, it’s then mixed on the back-end with other data sources that, as end-users, we’ll never be aware.
Increasingly, identifiable data collection is happening in more dimensions than are ever understood by most users. Some apps now offer “general” surveys or take note about group preferences, but are really harvesting detailed notes that track us individually.
Are we comfortable with all of this?
Let’s look at China today. The government is building a huge system to track every individual’s social reputation. Why shouldn’t good people be recognized and rewarded? Yet it’s not just a reward. Authorities can use that reputation as a means of direct influence and control – who gets jobs, travel and educational opportunities.
The Chinese government can aggregate and mine phone and app online activity, reported recorded personal interactions, and all financial transactions. In China, every individual will be monitored at a micro-level. Everything people do will be auditable forever.
Now, back to Facebook: Recently there was an online “fun” app in which users were encouraged to submit two pictures of themselves, 10 years apart. Privacy experts suspect that this was a thinly disguised excuse to collect a massive amount of training data, to train algorithms at a huge scale. Of course, all of this makes that vast Facebook photo library even more commercially valuable. If you submitted your precious selfies, you helped a machine learn how to erode one more layer of your privacy.
When we compare China with our freedom-oriented Western culture, are we really aiming to get somewhere much different? I fear that platforms like Facebook have taken us many steps down that darker road.
Much of the data mining we’re talking about is about training recognition algorithms. I’m a big fan of the mathematics of machine learning, but I’m not so sure it can be ethically deployed at scale “for good.” Much has been written about the way machine learning algorithms at scale can be taught prejudices and learn bad behaviors, or used as a pretense and shield for ultimately unethical practices.
Beyond that, we should be aware that machine learning is also forming the basis of much of today’s drive towards process automation. Increasingly, intelligent machine-based automation – powered by deep learning and artificial intelligence – will replace many of the jobs of many low-skilled people.
I don’t believe in protecting jobs that could otherwise be intelligently automated. But those users who aren’t careful about “donating” their data might find it used to automate them out of relevancy. There could come a time when companies that own the resulting “intelligence” will own everything there is of value.
There is an implied social contract between people that assumes a basic level of goodness in all people. But too many forget that Facebook is a for-profit company, not a trusted confidante or even a neutral platform. Even if we believe that online privacy is already a lost cause, we’d be wise to remember one thing: not everything we do needs to be exposed and handed outright to commercial entities.
Trust should be a hard thing to earn, and for trust in third parties, constantly re-validated. We need to keep in mind that passive data sharing is a deliberate trust decision. I’m not suggesting we turn off the Internet, or give up on tech-based networking with our friends and family. But as we said back in my Air Force days – “The price of freedom is eternal vigilance.”
Facebook may be where your friends are, but it isn’t your friend.
With data science as the sexiest job of the 21st century, it’s just difficult to disregard the continuing importance of data, and our ability to analyze, organize, and contextualize it. — and the organizations that recruit them — Data Scientists keep on riding the peak of an unbelievable rush of innovation and technological progress. While having a solid coding ability is significant, data science isn’t about software engineering. Truth be told if you have a decent experience with Python you’re all set. So comes the study of statistical learning, a theoretical system for ML drawing from the fields of statistics and functional analysis. Why study Statistical Learning? It is critical to comprehend the thoughts behind the different methods, so as to know how and when to utilize them. One needs to comprehend the easier techniques first, to get hands on the more modern ones. It is essential to precisely assess the performance of a method, to know how well or how badly it is functioning. Also, this is an exciting research area, having significant applications in science, industry, and finance. Let’s see some important statistical techniques in Python every data scientist must knowLinear Regression
In statistics, linear regression is a strategy to anticipate a target variable by fitting the best linear connection between the dependent and independent variable. The best fit is finished by ensuring that the sum of all the distances between the shape and the genuine perceptions at each point is as little as could reasonably be expected. The fit of the shape is “ideal” as in no other position would deliver less error given the choice of shape. Two significant kinds of linear regression are Simple Linear Regression and Multiple Linear Regression. Simple Linear Regression uses a single independent variable to anticipate a dependent variable by fitting a best linear relationship. Multiple Linear Regression utilizes more than one independent factor to foresee a dependent variable by fitting a best linear relationship.Logistic Regression
Logistic regression is an arrangement strategy that classifies the dependent variable into multiple categorical classes (i.e., discrete qualities dependent on independent factors). It is additionally a supervised learning technique acquired from the field of statistics. It is utilized for grouping just when the dependent variable is clear cut. At the point when the target label is numerical, utilize linear regression, and when the target label is binary or discrete, use logistic regression. Grouping is partitioned into two sorts based on the quantity of output classes: Binary characterization has two output classes, and multi-class classification has multiple output classes. Logistic regression means to locate the plane that isolates the classes in the most ideal manner. Logistic regression isolates its output utilizing the logistic Sigmoid capacity, which restores a likelihood value.Tree-Based Methods
Tree-based strategies can be utilized for both regression and classification problems. These include stratifying or segmenting the predictor space into various basic areas. Since the arrangement of parting rules used to section the predictor space can be summed up in a tree, these kinds of approaches are known as decision-tree methods. The techniques beneath develop various trees which are then combined to yield a single consensus prediction. Bagging decreased the variance of your forecast by creating extra information for training from your unique dataset utilizing combinations with redundancies to deliver multistep of a similar carnality/size as your original data. By expanding the size of your training set you can’t improve the model predictive force, however, decline the change, barely tuning the prediction to the expected outcome. The random forest algorithm is in reality fundamentally the same as bagging. Additionally here, you draw arbitrary bootstrap samples of your training set. Nonetheless, in the bootstrap tests, you additionally draw an arbitrary subset of features for training the individual trees; in bagging, you give each tree the full arrangement of features. Because of the random feature selection, you make the trees more independent of one another compared with ordinary stowing, which regularly brings about better predictive performance (because of better variance-bias trade-offs) and it’s additionally quicker, in light of the fact that each tree gains just from a subset of features.Clustering
Clustering is an unsupervised ML method. As the name proposes, it’s a natural grouping or clustering of data. There is no predictive modeling like in supervised learning. Clustering algorithms just decipher the input data and clusters in feature space; there is no predicted label in clustering.K-means clustering
K-means clustering is the most generally utilized clustering algorithm. The rationale behind k-means is that it attempts to limit the variance inside each cluster and maximize the variance between the clusters. No data point has a place with two clusters. K-means clustering is sensibly effective in the feeling of partitioning of data into different clusters.Hierarchical clustering

Big Data can easily get out of control and become a monster that consumes you, instead of the other way around. Here are some Big Data best practices to avoid that mess.
Big Data has the potential to offer remarkable insight, or completely overwhelm you. The choice is yours, based on the decisions you make before one bit of data is ever collected. The chief problem is that Big Data is a technology solution, collected by technology professionals, but the best practices are business processes.
Thanks to an explosion of sources and input devices, more data than ever is being collected. IBM estimates that most U.S. companies have 100TB of data stored, and that the cost of bad data to the U.S. government and businesses is $3.1 trillion per year.
And yet businesses create data lakes or data warehouses and pump them full of data, most of which is unused or ever used. Your data lake can quickly become an information cesspool this way.
The most basic problem is a lot of the handling of this data is partially or totally off base. Data is either collected incorrectly or the means for collecting is not properly defined. It can be anything from improperly defined fields to confusing metric with imperial. Business, clearly, grapple with Big Data.
That’s less of a problem with regular, routine, small levels of data that is used in business databases. To really foul things up you need Big Data, with petabytes of information. Because the data scales, so does the potential for gain or for confusion. So getting it right becomes even more important.
So what does it mean to ‘get it right’ in Big Data?Big Data Best Practices: 8 Key Principles
The truth is, the concept of ‘Big Data best practices’ is evolving as the field of data analytics itself is rapidly evolving. Still, businesses need to compete with the best strategies possible. So we’ve distilled some best practices down in the hopes you can avoid getting overwhelmed with petabytes of worthless data and end up drowning in your data lake.
1) Define the Big Data business goals.
IT has a bad habit of being distracted by the shiny new thing, like a Hadoop cluster. Begin your Big Data journey by clearly stating the business goal first. Start by gathering, analyzing and understanding the business requirements. Your project has to have a business goal, not a technology goal.
Understanding the business requirements and goals should be the first and the most important step that you take before you even begin the process of leveraging Big Data analytics. The business users have to make clear their desired outcome and results, otherwise you have no target for which to aim.
This is where management has to take the lead and tech has to follow. If management does not make business goals clear, then you will not gather and create data correctly. Too many organizations collect everything they can and go through later to weed out what they don’t need. This creates a lot of unnecessary work if you just make abundantly clear up front what you do need and don’t collect anything else.
2) Assess and strategize with partners.
A Big Data project should not be done in isolation by the IT department. It must involve the data owner, which would be a line of business or department, and possibly an outsider, either a vendor providing Big Data technology to the effort or a consultancy, to bring an outside set of eyes to the organization and evaluate your current situation.
Along the way and throughout the process there should be continuous checking to make sure you are collecting the data you need and it will give you the insights you want, just as a chef checks his or her work throughout the cooking process. Don’t just collect everything and then check after you are done, because if the data is wrong, that means going all the way back to the beginning and starting the process over when you didn’t need to.
By working with those who will benefit from the insights gained from the project, you ensure their involvement along the way, which in turn ensures a successful outcome.
3) Determine what you have and what you need in Big Data.
Lots of data does not equate good data. You might have the right data mixed in there somewhere but it will fall to you to determine it. The more haphazardly data is collected, the more often it is disorganized and in varying formats.
As important as determining what you have is determining what you don’t have. Once you have collected the data needed for a project, identify what might be missing. Make sure you have everything before you start.
The bottom line is sometimes you have to test the data it and review the results. You might be surprised to find you are not getting the answers you need. Best to find out before you plunge head first into the project.
4) Keep continuous communication and assessment going.
Effective collaboration requires on-going communications between the stakeholders and IT. Goals can change mid-way through a project, and if that happens, the necessary changes must be communicated to IT. You might need to stop gathering one form of data and start gathering another. You don’t want that to continue any longer than it has to.
Draw a clear map that breaks down expected or desired outcomes at certain points. If it’s a 12-month project, check in every three months. This gives you a chance to review and change course if necessary.
5) Start slow, react fast in leveraging Big Data.
You first Big Data project should not be overly ambitious. Start with a proof of concept or pilot project that’s relatively small and easy to manage. There is a learning curve here and you don’t want to bite off more than you can chew.
Choose an area where you want to improve your business processes, but it won’t have too great of an impact in case things go wrong or badly. Also, do not force a Big Data solution approach if the problem does not need it.
You should also use Agile techniques and the iterative approach to implementation. Agile is a means of operation and it is not limited to development. What is Agile development, after all? You write a small piece of code, test it eight ways from Sunday, then add another piece, test thoroughly, rinse, repeat. This is a methodology that can be applied to any process, not just programming.
Use Agile and iterative implementation techniques that deliver quick solutions in short steps based on current needs instead of the all-at-once waterfall approach.
6) Evaluate Big Data technology requirements.
The overwhelming majority of data is unstructured, as high as 90% according to IDC. But you still need to look at where data is coming from to determine the best data store. You have the option of SQL or NoSQL and a variety of variations of the two databases.
Do you need real-time insight or are you doing after-the-fact evaluations? You might need Apache Spark for real-time processing, or maybe you can get by with Hadoop, which is a batch process. There are also geographic databases, for data split over multiple locations, which may be a requirement for a company with multiple locations and data centers.
Also, look at the specific analytics features of each database and see if they apply to you. IBM acquired Netezza, a specialist in high-performance analytics appliances, while Teradata and Greenplum have embedded SAS accelerators, Oracle has its own special implementation of the R language used in analytics for its Exadata systems and PostgreSQL has special programming syntax for analytics. So see how each can benefit your needs.
See also: Big Data virtualization.
7) Align with Big Data in the cloud.
The first is using it to rapidly prototype your environment. Using a data subset and the many tools offered by cloud providers like Amazon and Microsoft, you can set up a development and test environment in hours and use it for the testing platform. Then when you have worked out a solid operating model, move it back on premises for the work.
8) Manage your Big Data experts, as you keep an eye on compliance and access issues.
Big Data is a new, emerging field and not one that lends itself to being self-taught like Python or Java programming. A McKinsey Global Institute study estimates that there will be a shortage of 140,000 to 190,000 people with the necessary expertise this year, and a shortage of another 1.5 million managers and analysts with the skills to make decisions based on the results of analytics.
First thing that must be made clear is who should have access to the data, and how much access should different individuals have. Data privacy is a major issue these days, especially with Europe about to adopt the very burdensome General Data Protection Regulation (GDPR) that will place heavy restrictions on data use.
Make sure to clear all data privacy issues and who has access to that sensitive data. What other governance issues should you be concerned with, such as turnover? Determine what data, if any, can go into the public cloud and what data must remain on-premises, and again, who controls what.
Business analysis is a process to analyze an organization’s business needs and identify opportunities to improve or exploit. Business analysis is theBusiness Analysis Disciplines
Business analysis is a broad term that includes a number of different disciplines. There are three main types of business analysis: functional, process and organizational. Functional business analysis looks at the current system to see how it works and what the customer needs. Process business analysis looks at how the process is executed by examining its steps and workflow. Organizational business analysis examines the corporate culture and how it performs in relation to customer needs, market conditions, competition, etc. A great way to increase your chances of success in any type of business analysis is by bringing together people withBelow we will list down the important business analysis techniques: SWOT Analysis
A SWOT analysis is a quick and simple way to identify the strengths, weaknesses, opportunities and threats of a business. A SWOT analysis is an instrument that is used to compile information about the company, its strengths, weaknesses, opportunities and threats. It is a very practical organizational tool that helps in analyzing performance and potential of the business. This technique identifies significant aspects of a business or organization so it can take steps in the right direction with clear strategies for success. SWOT analysis is commonly used in smaller businesses and startups.MOST Analysis
MOST analysis is a common form of qualitative research that helps to determine which purchasing motivations are most important for individual consumers. MOST analysis is a process where the researchers ask the consumers what they think motivates them to purchase a certain product and how much they value each motivation. The survey consists of five motivations – money, other people, status, image and fear of missing out. The survey asks respondents which two they consider most important or how happy they are with each aspect among participants.Business Process modelling
Business process modelling is the process of analyzing your business processes and then providing a diagram that identifies where efficiencies can be made. Business Process Modelling is important for any company looking to improve its operational efficiency. It can help you identify what processes are most time consuming, which ones are redundant and what could be done differently to make your business more productive. Business Process Modelling also provides a blueprint for future growth opportunities, by measuring the potential impact of new technologies on company operations.Use Case Modeling
The use case model is a representation of the system being developed. The process involves identifying stakeholders, actors, and use cases. The use case model is a representation of the system being developed. The process involves identifying stakeholders, actors, and use cases. This method can be used by business analysts to determine the requirements of a system from an end user’s perspective. It will also help them identify gaps that need to be filled in by software development teams. Use Case modelling is an integral part of agile software development because it helps engineers understand how the product will be used and what it must accomplish during each stage of its lifecycle.Brainstorming
Brainstorming in business analysis is a way of generating new ideas and solutions for problems. It’s a collaborative process that involves many people. Brainstorming is important to businesses because it helps increase productivity, creativity, and problem solving skills. This process also gives workers a chance to think about their own ideas without the pressure of having to come up with an answer immediately. It can be challenging to get people from all levels in an organization involved in brainstorming sessions. But it’s worth the effort because the more diverse viewpoints that are included, the better solutions can be found.Non-functional Requirement Analysis
Non-functional requirements are often overlooked, but they are the most important part of a software. These requirements include security, reliability, scalability, usability and accessibility among others. They are more difficult to test and assess than functional requirements because they are not code-based and their effects are not immediately visible.PESTLE Analysis
There are several factors that need to be taken into consideration when performing a PESTLE analysis.
